Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.

P2P SMS

P2P SMS stands for Person to Person SMS, or sometimes Peer to Peer SMS. It is a type of SMS that flows between two end users via their individual Home Networks. It is distinctly different from A2P SMS in that it is easily replaced by OTT messaging such as Whatsapp. For more information, see our FAQ page which distinguishes between A2P and P2P SMS.
